specific Embodiment approach 1

[0012] Specific embodiment one: a kind of reed rhizome budding optimum rhizome size cultivation method of this embodiment is to carry out according to the following steps:

[0013] 1. Collection of reed rhizomes in the wild: During the budding period of plant rhizomes in the middle and late April of each year, sample points with uniform seedling growth in inland or seaside reed swamps are selected, and the rhizomes are excavated through small patches to reach horizontal rhizomes. The best digging depth is 20-30cm. After digging the rhizomes, put them in a black plastic bag, avoid sunlight, and spray water;

[0014] 2. Treatment of reed rhizomes: wash the excavated reed rhizomes, cut off the above-ground parts, keep the underground rhizomes as cultivation materials, select healthy rhizomes with a diameter of 4-7mm, cut them into 20cm long sections, and ensure that each There are at least 2 nodes in the small section, and the rhizome of reed to be cultivated is obtained;

specific Embodiment approach 2

[0019] Embodiment 2: This embodiment differs from Embodiment 1 in that: the optimum digging depth described in step 1 is 25 cm. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0020] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the aboveground part described in step 2 includes aboveground stems, shoots and leaves. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a cultivation method for an optimum rhizome size for budding of phragmites australis rhizomes, relates to the technical field of ecological engineering, and in particular relates to a vegetative propagation method for plants. The method aims to solve the problems of long germination time, a low germination rate and a low survival rate of seedlings in a current rhizome propagation method. The method comprises the following steps: 1, collecting wild phragmites australis rhizomes; 2, treating the phragmites australis rhizomes; and 3, performing cultivation, and performingdetection in the budding process of the rhizomes. The method provided by the invention is used for cultivating the phragmites australis rhizomes; and the method has the advantages of rapid reproduction, a high survival rate, saved costs and the like, is suitable for providing the seedlings for recovery of inland and coastal phragmites australis marshes, and has important practical significance and application value.

Description

technical field [0001] The invention relates to the technical field of ecological engineering, in particular to a method for asexual reproduction of plants. Background technique [0002] Reed (Phragmites australis) is a perennial rhizome-type grass, which is widely distributed in the world and can be distributed in both freshwater and saltwater swamps. It is one of the main types of herbaceous swamps in my country. Phragmites reed has two propagation methods: seed propagation and branch propagation, but it is a typical clonal plant, and the natural population mainly relies on vegetative propagation to supplement and update. The creeping rhizomes of Phragmites reed are well developed, the root zone can reach several meters in length, and the depth can reach more than 1m below the surface soil. [0003] Reed has a wide range of economic value: 1. The crude protein content in the vegetative growth period is the highest among grasses, and it is an excellent feed; 2. The reed st...
